SPIKE AND BOLT EXTRACTOR.

SPECIFICATIQN forming part of Letters Patent No. 301,799, dated July 8, 1884.

' Application filed May 14, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that, I, JAMES S. CA PBELL, of Coal Valley, county of Allegheny, State of Pennsylvania, have invented or discovered a new and useful Improvement in Railroad Spike and Bolt Drawing Devices; and I do hereby declare thefollowing to be a full, clear, concise, and exact description thereof, reference being bad to the accompanyingdrawings,

making a partof this specification, in which likeletters indicating like parts I Figure 1 is a view in side elevation of my device as shown in the act of drawing a bolt.

Fig. 2 shows the same, but with the tongs or the construction of fiat-boats, barges, bridges, v

&c.when it becomes desirable for any reason to remove them. I readily accomplish this by the use of my improvement, the operation of which will be readily understood, and the construction of which is as follows:

Referring to the drawings, A represents the standards which support, by means of the notches n n a, the lever B.

I intend my improvement to be applied chiefly to two classes of work-first, the drawing of railroadspikes; second, the drawing of bolts. Hence I make the standards of two sizes. For railroad-spikes, I make the standards A'about eighteen inches in height, and

for bolts, which are much longer, and therefore require that the lever should be capable of being raised much higher, I make the standards A about forty-eight inches in height. The standards A are formed of one piece of metal, preferably (though two side pieces may be used) bent over or bowed. at the top, and standing upon abase-plate, and having notches n it it cut in the sides to support the pin a of the lever B.- The standards may be made of any suitable materi al-such' as malleable iron or they may be made of cast-iron or of wood.

The lever B, I make of steel, about five feetin length and one and threefourths inch square at the outer end, rounding it off at the other end, to form a convenient handle. The proportions of the lever may of course be varied; but those given I have found most convenient At the outer end of the lever B, I cut a rectangular opening, G, for the reception of the head-piece of the tongs.- This opening I make long enough to allow the head-pi ce O to swing quite freely in a plane parallel with the length of the lever. It is desirable that the headpiece 0 may swing in this way in order that the tongs B may be used either upon the inside or outside of a rail in removing spikes without the need of moving the whole device;

lever B will readily grapple the head of a spike or bolt and maintain a firm hold thereon until it is withdrawn.

Having described my improvement and its mode of construction, I claim as new and desire to'secure by Letters Patent of the United States In a'railroad spike and bolt drawing device, a suitable notched standard and a lever removably and adjustably supported thereon, in combination with suitable lazy-tongs pivoted to a reversible head-piece, which is in turn detachably connected to the lever, sub- Stantially as andfor the purpose set forth.

In testimony whereof I have hereunto-set my hand.
